Thermal Bonds of Buildings Structures in Energy Conservation–A Case Study

Abstract

From energy point of view, very actual topic in Czech Republic is redevelopment of concrete constructions in buildings. The article describes theoretical and experimental evaluation of chosen thermal joints of particular building built from reinforced concrete skeleton. The building stands in the central Europe in Brno. Problematic joints of reinforced concrete construction with filling construction were identified using thermo-graphic method. Consequently method of numerical simulation of steady state of heat transfer in 2D was used in software CalA. The aim was to evaluate linear coefficient of heat transfer and to identify critically low temperatures on internal surfaces and the energy losses of chosen details.
